PEEPAREIj CARBID' OF CALQIUIVI'.

Application filed June 11, i908. Serial 3T0. 437,994.

.T all whom it may concern Be it known that-I, XAVIER linux51, a citi-.z'en of the United States, residing at Fruitvale, in the county ofAlameda and State of 5 California, have invented certain new and usefulImprovements in Prepared (an-bid ofiCal'cium, of which the following isa specifi'cationl My'inventionrelates to an improvement inpreparedcarbidsof calcium for use in the generationof: acetylene gas. 7

I amaware that a prepared carbid of cal. clum has been. heretoforeemployed for overcoining; the defects of common carbid of calcium being.very sensitive to dampness .or ,moisture, and-leaving as a residuum alayer. of. moist and. solid liine which cannot pass through theopeningsof thereceptacle egntainingthe carbid as used in thepro-"fluctlon ofthe gas,lby, which conditions the development. of such gascontinued long after the' carbidi ceases to'be indirect contact withthe-wateni but I am not aware that a prepared:- carbidof calcium hasbeen ever fects, and whereby a high percentage of light may be obtainedimmediately upon the use 3 5 thereof 1n the usual manner.

The use of a prepared ea-rbidof. calcium containing the elements addedthereto in accordance with my said invention results 1 in the'productionof ninety per cent. of light uiroma. given quantity of material, whereassaid product heretofore employed is capable of producing but forty percent. of light therefrom and this in a period approximating five minutesafter submersion. A quan- 4 5 tity of prepared carbid of calcium towhich has beenadded the elements. used in the preparation of the sameaccording to my invention-has not the tendency to form intoa singlelump'ormass which condition hashere- 5o toforebeen encountered in thepractice of generating gasby the'use of the carbidheretofore employedasset forth.

In preparing carbid for the purposes of my invention, it is essentialthat the following 5 5 method besubstantially followed, wherefore,

Itake a certain quantity of' carbid of cal- Patented ul 's? 1909.

ciuin as sold commercially, and add thereto the following. substances inthe order named and in quantities in proportion tothe carbid.

which I rcm-esent as having one hundred parts. towit: sugar one part,and thereupon petroleum one-fourth of one part; sugar one part, giucosefour and one-half parts, and sugar two and one half. parts. In thepreparation of said carbid I prefer to use sugar in the form of )owderrefined )etroleum such.

as kerosene, gasoleno, machine oilor the like, and the glucose inh'quidform heated. to the boiling point, by the use of which I obtain ,thebest results, the substances being; absorbed by the carbid as. well asforming a coatingtherefor.- By the use of the sugar. and glucose, asmentioned, I- obtain, among other things, the proper dissolution ofthelime in the generation of'tl'ie-gas.

Thecarbid together with the substances which I use in connectiontherewith are thoroughly llllXQCl by agitation.

To illustratethe combination of n y prepared cal-bid the parts.hereinbefore, men: tioned ma"-'be desi uiated ounds a re at- J b 1 abing one hundred and nine and. one-fourth 1 pounds a greater-or lessquantitylbeing produced' proportionately.

- The petroleum. as used in the preparation of. the carbid isadvantageous, among otherthings,v in preserving the carbid from theundue action of moisture.

In the preparation of, the carbidforsaid purposes the elements areagitated in a suit able vessel, or rotary drum. as eachsuccess iveingredient is introduced until the absorption thereof or coatingtherewith is effected. By the application of the elements mentioned inthe preparation of the carbides described, I secure the thoroughabsorption of, the elements and coating of the carbid} free from give itsome moisture, the product being properly dried by the last quantity ofsugar used so as'to prevent each piece or particle of carbid fromadhering to any other, the substances substantially combined and mixedas aforesaid accomplishing the obj ect, of my invention.

Having thus described my invention what I claim as new and desire tosecure by Lthalf parts of glucose, and two and one half fersPatentis:parts of sugar. 0
